Hello.

Is someone here using VoIPmonitor?

I am using just the sniffer and I found some pcap files that contain some odd streams.

For example, I have a file with 3 streams, but the weird stuff is that 2
streams are the same (e.g., have the same source address and port and same destination address and port).

Example:

“Source Address”,”Source Port”,”Destination Address”,”Destination Port”,”SSRC”,”Payload”,”Packets”,”Lost”,”Max Delta (ms)”,”Max Jitter”,”Mean Jitter”,”Status”
“6X.XXX.XXX.XXX”,34170,”1XX.XXX.XXX.XXX”,10602,277011456,”g711A”,7289,0,21.
303999999996449,21.265543809819981,0.073286945955809715,””
“1XX.XXX.XXX.XXX”,10602,”6X.XXX.XXX.XXX”,34170,2020146713,”g711A”,2099,0,36.
296999999998661,2.9025967411766738,0.97877393850963945,””
“1XX.XXX.XXX.XXX”,10602,”6X.XXX.XXX.XXX”,34170,325951803,”g711A”,4949,0,41.
879000000000815,4.5846492231155924,1.0537488536922062,””

The only thing that I could notice is that the first packet that had the new SSRC (325951803) has the marker bit on, but I could not find a reason for the SSRC change.

Any ideas of what could be causing that?

Thanks.
